When this plugin is active, the index links at the bottom of the home page (e.g. mysite.com/page/2) just send the user back to the home page instead of going to the next page. Deactivating the plugin resolves the issue.
We just noticed this so I think it may be related to the latest release (1.1.8) but don't know for sure.

I would like to point out one thing out to you, though, regarding your comment:

"For future queries of this nature, please note that our WooThemes Support Desk is the best channel with which to communicate with our WooThemes support team. :)"

That is in fact where I started this process 2 months ago. However, the WooThemes support team tried to blame the problem on the FB plugin, and said they couldn't help me, but that I should try posting over here.
